You are conflating completely different issues. One is on individuals taking personal responsibility. Totally agree. But that was not the point here. If your postulation applies to retail traders then paying sponsors are exempt from taking personal responsibility to act with integrity and honesty? I don't think so.
The world where traders take personal responsibility for THEIR choices.
Most don't retailers short don't .... because they are afraid to. So they find all kinds of reasons why it doesn't work. "If the shoe fits".
